EUROPEAN DIRECTIVES

CE MARKING AND SAFETY

TE200A products carry the CE mark in compliance with the essential requirements of the

European Low Voltage Directive 73/23/EEC of 19/2/73 (amended by the Directive

93/68/EEC of 22/7/93).

For safety reasons, TE200Aproducts installed and used in compliance with this User Manual

meet the essential requirements of the European Low Voltage Directive.

ELECTROMAGNETIC COMPATIBILITY (EMC)

For an industrial environment only, must not be used in domestic environments.

Eurotherm certifies that TE200Aproducts, installed and used in compliance with these

Instructions, meet the following EMC standards and enable the system which incorporates

them to comply with the EMC Directive, as far as the TE200Aproducts are concerned.

EMC test standards

Immunity Generic standard : EN 50082-2

Test standards : EN 61000-4-2, EN 61000-4-4, ENV 50140, ENV 50141

ENV 50204

Emission Generic standard : EN 50081-2

Test standard : EN 55011 ClassA

Product standard : IEC 1800-3 (second environment)

Internal EMC filters

EMC filters are incorporated in the TE200Ato reduce conducted emission in accordance with

the corresponding test standard.

EMC Guide

In order to help you reduce the effects of electromagnetic interference depending on the prod-

uct installation, Eurotherm can supply you with the 'Electromagnetic Compatibility'

Installation Guide (ref: HA 025464).

This guide lists the rules generally applicable for EMC.

DECLARATION OF CE CONFORMITY

A declaration of CE conformity is available on request.

Validation by Competent Body

Eurotherm has validated the compliance of TE200Aproducts with the European Low Voltage

Directive and with EMC standards through product design and laboratory testing.

The tests carried out on TE200Aproducts are listed in a Technical Construction File validated

by the LCIE (Central Laboratory for the Electrical Industries), a Recognised Competent Body.

Further information

For any further information, or if in doubt, please contact Eurotherm Controls where qualified

staff are available to advise or assist you with the commissioning of your installation.

PRECAUTIONS

Safety symbols

Important safety precautions and special information are indicated in the text of the manual by

two symbols:

This symbol means that failure to take note of the information given in this manual

may have serious consequences for the safety of personnel and may even result in

electrocution.

This symbol means that failure to take note of the information may

• have serious consequences for the installation or

• lead to the incorrect operation of the power unit.

These symbols must be observed for particular points.

However the whole of the manual remains applicable.

Personnel

The installation, configuration, commissioning and maintenance of the power unit should

only be carried out by personnel qualified and trained to work with low voltage electrical

equipment in an industrial environment.

Independent alarm

Given the value of the equipment controlled by TE200Aproducts it is the responsibility of the

user, and it is highly recommended, that an independent safety device (alarm) should be

installed. This alarm must be tested regularly.

Eurotherm can supply suitable equipment.

Chapter 1 IDENTIFYING THE CONTROLLERS

GENERAL INTRODUCTION TO THE TE200A SERIES

The TE200Aseries of controllers are thyristor units designed to control the electrical power in

industrial three-phase loads.

ATE200Aseries controller is made up of two channels, each comprising a pair of thyristors

connected in anti-parallel, and a direct (unswitched) channel.

The TE200Aseries is designed to control three-phase resistive loads:

• elements with a low temperature coefficient

• short-wave infrared elements (except for the 63A model).

Three-phase loads can be connected:

• in star without neutral

• in closed delta

The wiring of the controller is independent of the supply phase rotation.

The nominal line-to-line voltage ranges¡ from 200Vac to 500Vac.

The nominal currents, defined at an ambient temperature of 45°C, of TE200Aseries

controllers are between 16A and 63A, per phase.

Two-phase control of three-phase loadsIDENTIFYING THE CONTROLLERS

The unit is controlled by analogue signals.

The analogue input signals have two voltage ranges: 0 to 5V or 0 to 10V, and one current

range: 4 to 20mA.

Local control is possible via a potentiometer (10kΩ).

The +5V user-voltage output is provided for this purpose.

The electronics of TE200Acontrollers are self-supplied from the power voltage and do not

require external connections (unless specified otherwise).

The control function for TE200Aincludes line voltage squared (V2) compensation for line

variations in the range ±10% of the nominal voltage of the controller; stability is better than

±2%.

TE200A series controllers have two thyristor firing modes:

• Burst-firing - the modulation cycle is from 30 cycles at 50% power (15 cycles ON,

15 cycles OFF) to a modulation time of approx 6 seconds at very low and very high power

demands.

• Single-cycle (one cycle of firing and one cycle of non-firing at 50% power).

ATE200Acontroller is equipped with:

• A‘driver board’which implements the control function and EMC filtering, and provides

power for the electronics. This board is also responsible for the input signal and operating

mode configurations.

• A ‘firing board’which triggers thyristor firing.

The filter which provides immunity against electromagnetic interference is located between

the power phases.

The user terminal block below the controller is used for the input signal connection without

needing access to the inside of the controller.

A green LED, labelled ‘ON’, indicates thyristor firing and is located on the front facia.

TE200A power controllers are designed to be bulkhead or DIN rail mounted.

The 63A rated unit must be permanently fan-cooled.

The fan power supply is 115Vac or 230Vac (to be specified when ordering the controller).
